Is there a way to change multiple file type associations at once?

Had the same issue today, and found the source file for the preferences to batch update on mac.

File is located here:
'/Users/<<YOURUSERNAME>>/Library/Application Support/Adobe/Bridge 2026/AdobeBridgeOpenerPreferences.xml'

The tricky part was, the lines triggering Photoshop Beta, were just generic:
<item description="$$$/Bridge/OpenersXML/Description/ARQ=ARQ" extensions="arq" app_name="Photoshop">

Changing one file type association changed to an absolute path:
<item description="$$$/Bridge/OpenersXML/Description/Alias=Alias" extensions="pix" app_name="Adobe Photoshop 2026 27.6" app_path="/Applications/Adobe Photoshop 2026/Adobe Photoshop 2026.app">

What worked for me, was to open the file and search:
app_name="Photoshop">

Replace with:
app_name="Adobe Photoshop 2026 27.6" app_path="/Applications/Adobe Photoshop 2026/Adobe Photoshop 2026.app">

Save xml, and reopen bridge.

Now everything is opening in the PS version I want, and I still have beta installed. You will of course have to customize based on program version. Using VS code, bridge editing the pref immediately showed me the app_path change.

No, there is not (and I've been asking for this for at least 10 years).

There should be a command that let's (e.g.) Photoshop Beta controls to Photoshop 2026. Realizing that there may be issues, such as when capabilities and/or other applications move on. For example, when Flash was removed many years ago, there would have been issues in such a global change. But the extra time involved in dealing with this would have been insignificant to amount of time saved otherwise.
